Flow into the sample gas of aerosoloscope, be called for short sample flow 3, gas velocity is limited by existing conventional aerosoloscope, normally a fixed value, can't regulate, its value is generally 10L/min～40L/min.
The flue gas generating means can be set to smoking machine and solenoid valve.Air-flow (sample flow 1) flow velocity that flows out from the flue gas generating means must meet the requirement that cigarette detects and be provided with, and can not arbitrarily adjust, and detects according to difference to require its value at 1mL/min～1.8mL/min.Solenoid valve can communicate with surrounding air, detects according to cigarette to require to be provided with, and 2s is communicated with the smoking machine smoking cigarette usually, and 58s switches to draws ambient air, carries out repeatedly finishing up to cigarette smoking.
First order dilution is regulated mainly to play the concentration of sample flow is diluted rapidly, avoids gasoloid circulation pipeline is resulted in blockage.Simultaneously, guarantee the flow velocity coincidence detection requirement of sample flow 1.Its extension rate is set to 10～30 times, and mainly the requirement that detects according to cigarette is adjusted.
Second level dilution is regulated main guarantee flue gas aerosol concentration, is reached the requirement that the aerosol particle state stability meets aerosoloscope.Its extension rate is 5～20 times, and mainly according to gasoloid burst size in the detection cigarette sample aspiration procedure, and the valid analysing range of aerosoloscope is adjusted.
Auxiliary suction source adopts the device with stable flow speed control function, and task performance requires to reach 100mL/min～400mL/min.Its effect is to ensure that the flow velocity of sample flow 4 meets the setting value of aerosoloscope.
The beneficial effects of the utility model are: be connected design by improving the flue gas generating means with gas circuit between the gasoloid checkout equipment, adopting increases auxiliary gas air mix facilities and waste discharge device, set modes such as appropriate gas flow speed, regulate and when guaranteeing to gather the flue gas aerosol sample cigarette burn and suck and meet the requirements, and enter sample concentration in the detecting device in the valid analysing range of equipment.
The utility model has been realized the detection to cigarette flue gas aerosol, does not need to detect the special-purpose gasoloid checkout equipment of exploitation for cigarette smoke.Detect effect and obviously improve, realize the flue gas aerosol situation is analyzed more accurately.
